OIL-HOLE COVER OR CAP.

SPECIFICATION forming part of Letters Patent No.'642,860, dated February6, 1900.

To @ZZ whoml t may concern.-

Be it known that I, FRANK D. WINKLEY, a citizen of the United States,residing at Madison, in the county of Dane and State of Wisconsin, haveinvented certain new and useful Improvements in Oil-Hole Covers or Caps,of which the following is a specification.

My present invention pertains to covers for oil-holes, the constructionand advantages of which will be hereinafter set forth, reference beinghad to the annexed drawings, wherein- Figure l is a side elevation ofthe device, the cover or sleeve being shown in a position covering theopening in the body or post; Fig. 2, a similar view, the opening beinguncovered; Fig. 3, a vertical sectional View; Fig. 4, a perspective viewshowing the parts detached; Fig. 5, a horizontal sectional view on theline l l of Fig. 3; Fig. 6, a similar View on the line 2 2 of Fig. 3;Fig. 7, a perspective view of a modified form of the post or body, andFig. 8 a horizontal sectional view taken through the reduced portion ofthe body.

The object of my invention is to produce a simple and at the same timeeflicient oil-hole cover or cap and one in which the movable orrotatable part of the cover will be brought back to its closed positionafter the attendant 'has introduced the oil into the hollow bodyportion. l

Referring to the drawings, and more particularly Figs. l to 6,inclusive, A denotes the body or post of the device, hollow through thelower portion of its length and provided with a lateral opening B. Thelower end of the body or post is threaded, while the upper closed end isformed with a cross-slot C for the purpose of facilitating itsattachment to the part to which it is to be applied. Formed around theupper portion of the body A is a groove or channel D, said channel orgroove being eccentric to the axis or body, asis clearly indicated inFigs. 3, 4, and 5. The formation of this groove of course produces areduced stem E, which connects the upper and' lower portions of thebody, said stem of course being eccentric to the axis of the bodyproper.

As will be seen upon reference to Figs. 3, 4, and 5, the shallow portionof the groove or channel is formed upon thatside of the body in whichthe opening B is made, and at this Serial No. 712,785. (No model.)

point the stem E is drilled, forming a hole or seat F.

G indicates the outer cylindrical member or sleeve, having a portion ofits side cut away, forming an opening H. Upon the inner face of saidsleeve near its upper end is a orroove or channel I, while above theopening II a slot J is cut through the sleeve, said slot opening intothe groove or channel I, as shown in Figs. 3 and 5.

To secure the parts together and also to maintain the sleeve in itsclosed position relative to the opening B, I employ a spring K of theform illustrated in the drawings. The

spring is provided with an inturned end or thereof are made somewhatlarger than the internal diameter of the sleeve G, necessitating itsbeing twisted up, and thereby reduced in diameter and put under tensionor strain when the parts are to be assembled.

In assembling the parts the operator introduces end L into opening F.and draws or twists the spring into the groove or channel E, holding thespring by the end M. When the spring has been twisted about the stem Esuficiently to draw it into the channel, end or arm M will be in thedeepest portion thereof, so that the operator can slip sleeve G over theupper end of the body and down to place. When slot J comes opposite theoutwardlyextending arm M, said arm will spring therein and occupy theposition indicated in Figs. 2, 3, and 5. At the same instant that coilof the spring which is opposite the channel or groove I Will expand intoit, and thus lock the sleeve against endwise movement relative to thebody portion.

The parts are so proportioned and arranged that when they are assembledand the spring has expanded as far as it is possible forit to expandsleeve or member G will occupy the position indicated in Figs. l, 3, 5,and 6, wherein it will be noted that opening B is closed. By rotatingthe sleeve in the direction of the arrow, Figs. 5 and 6, the operatorcan uncover the opening B; but it is nec- IOO essary to hold the sleeve,for instantly it is released the spring will again expand and rotate thesleeve.

To facilitate the turning of the sleeve or shell, it is provided with aslightly-enlarged milled surface near its upper end.

The construction of the groove or channel D eccentric with reference tothe axis of the device is advantageous, for the reason that it enablesthe maker to drill hole F more readily than could be done were thesurface of the stem E back farther from the face of the body, also inthat it holds the hook L in place with more certainty, for the reasonthat there is not space enough between the parts for the hook to Workout after the sleeve has been passed down over the body or post to itsplace. In assembling the parts the eccentric formation of the slot isalso advantageous in that it affords space in which the hook or arm Lmay be forced back as the sleeve or outer member G is passed down toplace.

The groove I formed upon the inner face of the sleeve serves, as abovestated, to hold the -parts together; but it is manifest that the arm Mmay be relied upon solely, although this construction would not benearly as good as the other.

In Figs. 7 and 8 I have shown a construction of the post or body whereinthe slot corresponding to the groove or channel D is formed concentricwith the axis of the body portion. XVhile this formation of the slot isfeasible in the use of the device, still the eccentric formation is thepreferred one. It will be noted more particularly upon reference to Fig.5 that the arm or hook L, which is bent back quite sharply upon itself,engages one wall of the slot or opening J and that by so bending thisarm there is little or no liability of the spring slipping out of place,as might be the case were it bent at right angles or at an obtuse angle.

Having thus described myinvention, what I claim is l. In an oil-holecover or cap, the combination of a body portion; a sleeve or shellrotatably mounted thereon; a spring interposed between said parts; andmeans coacting with said spring, substantially as described,whereby thesleeve is held against endwise movement, is capable of being rotated alimited distance about the body portion, and is returned to adeterminate position relative to the body portion when released by theoperator. y v

2. In an oil-hole cover or cap, the combina` tion of a hollowr bodyportion provided with an opening; a sleeve or shell rotatably mo unt-`ed on said body portion and likewise provided with an opening; aspring-locking device interposed between said parts; and means coactingwith said device, serving to hold the parts against separation and torotate the sleeve a limited distance about the body portion, whereby theopenings are normally held out of alinement, substantially as described.

3. In an oil-hole cover or cap, the combination of a hollow body portionprovided with a lateral opening; a sleeve rotatably mounted thereon andalso provided with an opening; a coiled spring interposed between theadjacent side walls of said parts and having its ends attached to thebody and sleeve respectively; and means coacting with said springwhereby the openings are normally held out of alinement and endwisemovement of the sleeve is prevented.
